Mechanical Dinosaur Jaws Vs. Replica Borealopelta Body
Вставка

- Scientists have created powerful mechanical jaws, modeled after the mid-Cretaceous predator known as Acrocanthosaurus. Now it’s time to test it out on a recreation of Borealopelta’s armored body.

Yeah I can't believe how close he got to it while it's still hooked up and everything
Good thing it's a human operated machine
Human operated machines mess up sometimes- worse still, humans mess up like crazy lol
He's nuts for sticking his arm between those jaws like that. Please, for safety's sake, have a conversation with them about that.
This was really neat! I feel like the small panel on the Borealopelta made it sustain more damage. Also, the animal wouldn't have just stood there, and their net of ligament allowed them a remarkable amount of flexibility. Going after something in its prime is still a bad idea in nature, so I feel like this would be the 1 in 5 success ratio here.
But the ability to tear away osteoderms is amazing! Makes me wonder how many of the nodosaurs walked around with missing armor pieces.
Yes, of course in real life the predator would simply be afforded the opportunity to bite a motionless prey in the optimum position for its jaws, neither is it likely that every closure of the jaws would entail maximal bite force - unless it's going in for the coup de grace most bites on a resistant animal would be slashing and gouging rather than crushing, and thus cause massive blood loss. In such circumstances I feel the armour would offer more protection that this test would appear to suggest.
Seems impressive, but it's only a tiny peice and it's to the side, where the osteoderms are weaker. Borealopelta is too low slung for this attack to work, Acrocanthosaurus has to knock it on it's side first. Plus, it took quite a few bites to pull that off. Furthermore, I don't know if Carcharodontosaurs can close their jaws that quickly, it should be slower.
Yeah maybe, but just remember the speed with which modern day crocodiles close their mouth, the bulk of the destructive force in those jaws are the pressure they can excert per square inch.
In defense of Borealopelta, it would be difficult to get a bite of that magnitude off
2:58 omg be careful with that hand, it's still in the middle of those jaws..! You never know ..
If it would CLOSE..... Whole arm falls off the shoulder ..
Ya sure just stick your little arm in there... I’m sure nothing bad could ever happen.
Terrifying... Thought the armour would hold a little better. Great stuff here
interesting, although I'm not sure the bite speed was precise, the actual might have been slightly slower.
Ever watched a crocodile chomp on something?
I think it's not a valid test since nodosaurs and ankylosaurs were short-legged, flattened animals, for a predator to reach this part of his body he would have to lie down on the ground, the right thing would be to try to bite from above, which is kind of difficult since it is a very wide animal, and the keratin plates would make it very difficult for the teeth to hit something, they would just slip or probably break
It doesn't matter. The roof of the armor is still vulnerable to attacks.
Put your head in it for perspective!
That is truly terrifying! I am a lover of dinosaurs but I am glad they went extinct. Also, one last childish thing before I end this:
Big dino go *C H O M P*
Well, dinosaurs are still alive. You have a dinosaur on your profile pic.
@@risingmagpie9199 I was to comment the same
Birds are theropods dinosaurs.
I should clarify: I meant dinosaurs as they existed then, millions of years ago. I thought that was straightforward but I suppose not. And yes, I am fully aware that the avians of today are their descendants.
@@FyreMagyk67 Birds(a group of theropods that survived )already existed in the Mesozoic, lol.
But ok,i understood that you were referring to non-avian dinosaurs.
Final destination written all over it
That bite had momentum to it, and may not reflect the slower pressure building bite of an actual dinosaur...
idk, a gator or crock can close their jaws pretty quick, i'd imagine things like t-rex and acro can do it too.
@@FULLPOWERSSJALEX
Laws of inertia.
That could of been nasty at the end if it went off
the muscular neck of the dinosaur contributed to the bite force.
OUCH!!!! How strong is that bite!?

That’s pretty neat

That's amazing
Condemned criminals (specially kiddie diddlers) should be sentenced to be the guinea pig for a bite force test like this.
Let the T Rex have a Go😂
Neat but test this on a tyrannosaur and I am sure it will be more devastating on armor.
Just great! 👍👍👍😀
That's very cool,yet being 2 years maybe its not too accurate but it's far from inaccurate either but SO AWESOME
Awesome
would the teeth break before the borealopelta looked like that?
1:50 - So the megalosauridae have had impressive bite force afterall?
After tyrannosaurus the strongest bite of ant therapod was torvosaurus which was the largest megalosaurus
@@Megaguy12 And where did you get that information? There haven't been any tests in regards to the jaw strength of Torvosaurus as far as I'm aware.
@@Saberrex1 google
@@Megaguy12 You can check Google Scholar and confirm that there isn't any published study attempting to estimate the biteforce of Torvosaurus.
As far as I know the source of "Torvosaurus had the second strongest biteforce" comes from some guy on DeviantArt misinterpreting what mechanical advantage means.
Dude that is an Allosauroid. Not a Megalosaur.
Makes me wonder how the specimen at drummheller managed to reach adulthood without ever taking such a bite.
Well we don’t have 100% of the specimen’s body. Maybe those missing parts have some marks from a predator attack?
We know its coloration helped it to camouflage, so evasion was likely a prominent factor. If it had a method to hide its scent from predators as well, then it would be even harder to find.
Maybe it also had an unpredictable and aggressive response to novelties like that seen in the modern-day rhinoceros, enough to often dissuade predators from even approaching it if detected.
Nodosaurs were really formidable prey. You saw how well the armor protected its body. The first bite was superficial damage that can be recovered from. It was only the second that was lethal. So predators would have to bite hard enough to damage them in one or two bites while the animal is squirming around and trying to crush/cut its ankles. Nodosaurs didn't have tail clubs but their tails were still covered in hard and oftentimes sharp armor that would be dangerous to get hit with. It would be hard to bite one, even with a younger individual. And if it's too young a predator of this size wouldn't bother trying because it would be so little food, and if it DID try, the borealopelta would certainly die so we would never see an adult with a bite that came from its childhood.
Herbivores also generally grow quickly even with dinosaurs.
TL;DR: Borealopelta was squirmy and hard to bite so most of them would probably either just not get bitten, or they'd die as a result of it so finding a borealopelta with a healed over severe injury is unlikely
People are saying that they're surprised the armor didn't hold up but I actually think it held up amazingly well considering it was being bitten by an apex predator. The fact the rib got shattered, presumably in the second bite, goes to show how well the armor protected it. I mean in the first bite the borealopelta's armor didn't even come off, it just came loose. This was the kind of damage an animal could recover from if it gets out alive. It took two bites for it to become lethal, and that's amazing to me. I always thought the armor on these animals didn't work quite as well as people say, but honestly after this I can say it was VERY effective as armor. One bite from an apex predator causing superficial damage. Two bites causing near certain death, but still not even a bite as lethal as it'd be for most animals of its size... if you got that animal to a vet (somehow) it would probably have a chance of living. That's insane, you should have no chance of living when an acrocanthosaurus bites you squarely on the back lol
3:00 "Watson, fire!"
*[Phil Swift has entered the chat]*
This video has been a bit of a wake up since I always thought ankylosaurs and nodosaurs were impregnable in their armour…
3:07 I got real nervous when his arm was in the jaws 😰
That bite speed was too fast, no??
If we compare it to a crocodile it seems about right
Seemed slow to me.
@@noelfolz50 A crocodile bite is a specialist tool that evolved through the particular kind of ambush hunting the crocodilians engage in. A crocodile cannot chew nor can it slice out bite- size chunks of it's prey; having to flail around to get it to break into swallowable pieces. A corcdile needs all it's power in that snap and hold, then it drags its prey into the water and drowns it; it has feeble jaw opening muscles that a humans could hold a croc's mouth shut. This dino has entirely different hunting and feeding strategies.
The closely related Allosaurus was found to have adaptations for delivering fast bites in rapid succession. It’s likely that allosauroids in general like Acrocanthosaurus would also have such adaptations.
You do know thats exactly the same as this dinosaur right?
Is is a documentary film?
Is that the guy who helped develop xbox ?
Seamus Blackley is one of the creators of the original Xbox
But what are the chances that a predator would land a bite in the same exact area? Especially if the animal is not pinned down? I like these and I know their doing it to try and learn more and inspire others. Its a great demonstration, but calling it 100% accurate or making absolute assumptions kinda disproves the Methodology of the experiment.
How Strong was the Bite force exactly from Agrocantosaurus
10,000 pounds
@@theancientlands8259 now i now the biteforce a study from 2022 that saiy 8266 newton front biteforce and rear biteforce 16984 newtons and a scientist say the maximum possible biteforce was determined by testing how much bite force the teeth can withstand and that was 10 k newtons but 8266 is the more realistic
@@theancientlands8259 is that like how many tons. Is it around most carcharodontosaurids and even some spinosaurids? I know it's not as strong as some tyrannosaurs.
@@usmanya5110Ok, so I’ve done more research, and it says that the acro was around 8266 newtons, and the posterior bite force was around 16894 newtons, this is stronger than some carcharodontosaurids, but not stronger than most tyrannosaurids.
1.8 tons.
Acro's much bigger relatives Giganotosaurus, Mapusaurus, Tyrannotitan had far more powerful bite force than it.
Imagine how deadly their bite was
Hot take: the mechanical jaws here were not going that fast, people in the comments section are just nitpicking.
Well i'm glad these things aren't around anymore 😂
Terrifying creature.

Wait till you hear about Mapusaurus
@@ivangigliotti3693 meh, mapusaurus is just like most carcharodontosaurids, acro gets more reputation because of general looks
@@swiftwyvern8106 Yeah but I referenced Mapusaurus because it's the largest
@@ivangigliotti3693 No? Giganotosaurus is the largest Carcharodontosaurid, and the second largest theropod overall just behind Spinosaurus.

bruh how they find real dinosaur meat 💀💀💀
It isn't. They said in the video it's made of putty and stuff.
Whos trying to build Jurassic park from scratch
For the record the T. rex wouldn’t have stayed completely still and moved it’s lower jaw like that. These tests aren’t realistic to what it the damage would be, at all. It’s like comparing how you eat normally and then someone putting some food in your mouth and asking you to close your jaw on it. Doesn’t make sense
That's an excellent point, and we actually took it into account with the forces. The total force we applied models both jaw closing muscles and the downward force of the upper jaw applied by the neck musculature. For practical purposes, we had to actuate all the motion in the lower jaw, so it's not a perfect model (they never are), but the dynamics should be broadly accurate. Acrocanthosaurus did not have the best armor busting anatomy, so it is perhaps not a surprise that the model does not do Tyrannosaur level damage. A rex was much better equipped to break armor, but it would not show up for another 35 million years.
I was thinking the same thing. Borealopelta would also not stand still It would move around. The osteoderms would destroy those teeth.
@@MichaelHabib true and ankylosaurs were also wide. Making their armor more effective. That little piece is useless
Michael Habib that’s good but what’s the point of even doing the test if it’s not going to show how it would’ve bitten? Why do I at all if any of the results you get will come with the caveat of well it didn’t actually bite like that. Seriously compare a crocodile and how it actually bites and some robotic Crocodile jaws. I feel like these tests would set you back in actually understanding how this creature moved
@@matthiasfloren2610 The idea was to model an angled bite, i.e. the predator turning its head to get a shearing attack. We did that specifically because nodosaurids were so wide bodied that it's the only feasible attack approach. Sort of a "worse case scenario" setup. Which is one reason I'm so impressed by the armor - it did very well, even with some fairly unfair assumptions stacked against it. There's also a potential application aspect to this project that benefits from having tests of smaller sections of armor.
jusus christ, its clear a trex can crush a elephants head with one bite.

The lie of the videos does not prove that it is the Acrocanthosaurus not the same as the gigas apart from the meat
